SHIPPING CARRIER FOR ROLLS Filed June 21, 1955 .VE 2UP Patented Feb. 2,1937 UNITED STATES PATENT OFFICE SHIPPING CARRIERFOR ROLLS IllinoisApplication June 21,

1 Claim.

This invention relates to a shipping carrier for rolls and moreparticularly to a shipping carrier for gelatin duplicating rolls.

It has heretofore been customary to use metal, or wood carriers forgelatin duplicating rolls. This practice, however, is relativelyexpensive, since the carriers are not generally reused but are thrownaway.

It is therefore an important object of this invention to provide arelatively inexpensive shipping carrier for gelatin duplicating rollsand the like, wherein the carrier is a tube or core made from fibrousmaterial, such as chip board, straw board, mechanical wood pulp or thelike.

It is a further important object of this invention to provide a shippingcarrier for gelatin duplicating rolls and the like that can be used atlittle expense in the shipping of the rolls and that is of suchdimensions as to fit over the usual sizes of spindles employed onduplicating ma chines.

Other and further important objects of this invention will be apparentfrom the disclosures in the specification and the accompanying draw- 25ing.

This invention (in a preferred form) is illustrated in the drawing andhereinafter more fully described.

On the drawing:

Figure 1 is a side elevational view of a shipping carrier for gelatinduplicating rolls with the roll wound thereon.

Figure 2 is an end elevational view of the same.

Figure 3 is a fragmentary enlarged view showing the leader strip of thegelatin roll and a shipping carrier of my invention, preparatory towinding the gelatin strip thereon.

Figure 4 is a sectional View of the shipping carrier mounted on aspindle with the gelatin roll being unwound.

Figure 5 is a fragmentary enlarged sectional view of the end of theleader strip.

As shown on the drawing:

The reference numeral l designates generally a shipping carrier forgelatin duplicating rolls or the like embodying the principles of myinvention. As shown in Figs. 1 and 2, a roll ll of gelatin coated stripmaterial I2 is wound upon the shipping carrier III for storage andtransportation purposes.

The gelatin strip material I2 is provided with a leader strip l3 ofcloth, fiber backing stock, or the like that is secured to the end ofthe gelatin strip by stitching or by means of adhesive, as indicated atI4, or that is a continuous and integral part of the backing materialused as a base for mounting the gelatin of the roll itself. The end ofthe leader strip [3 is reduced 1935, Serial No. 27,657

toform a tapered portion IS, the leading end of which is suitablyreinforced, as by a metal strip l6. O-ne manner of engaging the end edgeby the metal strip 16 is illustrated in Fig. 5, wherein the metalstripl6 and end edge I! are folded about themselves and flattened somewhattogether. The reinforced end I8 thus formed is of increased thicknessbeyond that of the leader strip itself.

The shipping carrier Ill comprises a core or tube preferably formed ofcheap fibrous material, such as paper board, straw board, or the like.In dimensions, the core H3 is slightly longer than the width of thegelatin strip l2 so that its ends project beyond the roll II asindicated at I9. The inside diameter of the carrier ID is not less than1 4 inches, so that it may be slipped over any of the customary sizes ofspindles used in rewinding the gelatin roll. The thickness of the wallof the carrier tube or core I0 is preferably between the limits of 1 5inch and inch, so as to provide the necessary strength and at the sametime be comparatively light.

A slot is provided in the carrie ID for receiving the reinforced end I8of the leader strip. Said slot It] extends longitudinally of the tube orcore and its ends are spaced equally from the ends of said core. Thelength of the slot 20 is substantially the same as the width of thereinforced end I6 and the width of the slot 20 is substantially the sameas the thickness of the reinforced end l8. Thus, when the reinforced endI8 is inserted into the slot 20, it fits snugly therein and is heldfrictionally against removal. It should be noted that the thickness ofthe wall of the core 90 is such that the reinforced end I 8 may beinserted into the slot and substantially fill the same withoutprojecting into the interior of the core and without forming anyprojection beyond the outer surface of the core. The reinforced end IBtherefore does not interfere with the insertion of a spindle 2| withinthe core, as is necessary in rewinding the gelatin strip material fromthe roll ll onto a permanent spindle for use in a duplicating machine.

In starting the winding of the gelatin strip material onto a shippingcarrier of my invention, the reinforced end I8 is inserted into the slot20, thereby centering the strip material with respect to the ends of thecarrier. The leader strip I3 is then wrapped around the core l0 and thewinding of the gelatin strip material continued to form the roll II.

It will be appreciated that the length of the carrier l0 may be variedto suit different widths of gelatin rolls, but it is preferable toprovide the same length of slot 20 regardless of the overall length ofthe carrier. Accordingly, the length of the reinforced end l8 alsoremains the same, regardless of the width of the gelatin roll, so thatthe reinforced end may always be properly fitted into and retained inthe slot 20 of any particular carrier.

I am aware that many changes may be made and numerous details ofconstruction may be varied through a wide range without departing fromthe principles of this invention, and I, therefore, do not purposelimiting the patent granted hereon otherwise than necessitated by theprior art.

I claim as my invention:

In a duplicator roll assembly in which an elongated tube frictionallyengages a smooth spindle but is slidable thereon because of the absenceof protuberances on the inner face of the tube, an elongated tube offibrous material, such as paper board, provided with a longitudinallyextending slot in the wall thereof and disposed intermediate the endsthereof, an anchor member of substantially the thickness of the wall ofsaid tube laid in said slot, and a roll of gelatin having a leader stripsecured to said anchor member, said tube providing a core on which aroll of gelatin is anchored and wound, and providing with said gelatinroll and its anchor an assembly readily slidable over a smooth spindlefor use in a duplicator.
